Option 128GB (64GBx2) DDR5 6400

  • ECC detects and corrects data errors for server reliability
  • Registered DDR5 6400 CL60 delivers 51200 MT/s throughput
  • Dual 64 GB modules provide 128 GB total capacity
  • Hynix ICs tested on auto sorting equipment ensure consistent quality
  • On-module thermal sensor monitors temperature up to 85 °C

Capacity and audience

This V-color kit delivers 128 GB across two 64 GB DDR5 RDIMMs rated at 6400 MT/s with CL60 timings. It is built for server and workstation motherboards that require registered ECC memory and will not function in standard desktop or laptop platforms.

Thermals noise and power

Modules operate at 1.1 V and include an on-board thermal sensor that monitors temperature across the 0 to 85 °C range to guard against overheating. Registered buffering and ECC correction add stability without introducing audible noise or measurable extra power draw under normal loads.

Build quality and connectors

Each stick uses 288-pin DDR5 RDIMM connectors populated with Hynix ICs sorted by automated test equipment. The registered design and ECC support mean the kit fits only compatible server or workstation slots, so builders needing unbuffered desktop memory must choose a different product.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules and what step is often missed?

Align the notch on each 288-pin module with the motherboard slot key, press down evenly until both retention clips click, and confirm the board detects 128 GB at DDR5 6400 CL60 in BIOS.

What maintenance or replacement will the Hynix IC ECC RDIMM kit need later?

The built-in thermal sensor monitors temperature up to 85 °C; keep server airflow clean so the sensor never triggers throttling, and replace a module only if ECC logs report uncorrectable errors.

What limit appears first under sustained load on these 1.1 V DDR5 6400 modules?

The operating temperature ceiling of 85 °C is the first hard limit; if case airflow cannot keep the modules below that, the thermal sensor will reduce performance to protect the Hynix ICs.
